A TVS, or transient voltage suppressor, is a type of protective semiconductor device used in high voltage applications to protect against overvoltage transients. Varistors, or voltage-dependent resistors, and metal oxide varistors (MOVs) are two common types of TVS that serve this purpose. B72207S0200K101 is one such varistor that has many applications in both domestic and commercial settings. In this article, we\'ll discuss the application field and working principle of B72207S0200K101.

The B72207S0200K101 is a bi-directional varistor with PN junction technology used in high voltage applications. It is a two-terminal device with a unipolar dispersive charge structure that allows it to provide reliable protection from overvoltages. This varistor has an operating temperature range of -55°C to +125°C and can be used in temperatures up to +175°C, while its minimum capacitance is rated at 210pF at 1V. It has an average voltage rating of 280V, a peak voltage rating of 250V, and a rated surge current of 2kA.

When it comes to its application field, the B72207S0200K101 can be used in a wide range of high-voltage applications, including surge protector circuits, LED lighting systems, motor control circuits, and power supplies. It is designed to protect against overvoltage transients and has been tested to meet the requirements of EN61000-4-2 standard. It is also highly resistant to parasitic inductance, making it ideal for use in high-voltage capacitor applications.

The working principle of the B72207S0200K101 is that it acts as a voltage-dependent resistor. When the voltage across the device exceeds its peak rating, its resistance decreases rapidly, allowing it to dissipate the excess energy. As the voltage across the device drops back down below the peak rating, the resistance rises again and the device returns to its low-resistance state. This process of rapidly changing resistance acts as a kind of protection from overvoltage transients, preventing them from damaging the delicate components of the system.

In addition to its use in surge protection circuits, the B72207S0200K101 is also used in LED lighting systems. It provides overvoltage protection for the LEDs, helping to extend their life and reliability. It is also used in motor control circuits, as it helps protect the motor from sudden voltage spikes that can damage the electronics used in controlling the motor. Finally, the B72207S0200K101 is often used in power supplies, such as AC/DC converters, to provide overvoltage protection for the integrated circuits used to regulate the power supply.

The B72207S0200K101 is a bi-directional varistor with PN junction technology and high voltage applications. It is rated for a peak and average voltage of 250V and 280V, respectively, and has a minimum capacitance of 210pF. It is highly resistant to parasitic inductance, which makes it well-suited for use in capacitor applications. Its application field includes surge protection circuits, LED lighting systems, motor control circuits, and power supplies. The device works by acting as a voltage-dependent resistor that rapidly changes resistance when the voltage across it exceeds its peak rating, thus protecting against overvoltage transients.
